Train services were disrupted in the Australian city of Melbourne on Monday night due to power failures as the city experienced its hottest night in 108 years.
The temperature rose to about 43.6°C on Monday and reached a peak of 37°C in the middle of the night, remaining at an average of 34°C throughout the night.
As the heat soared electricity demand in the state of Victoria rose to a record 10,105MW, compared with average summer highs of nearly 6,500MW, according to the Australian Energy Market Operator, a group of energy industry bodies.
This resulted in power failures and cancellations on 12 of the 17 lines reported by the city's rail network operator Metro, which led to cancellations of over 140 train services.
Other heat-related line problems including lack of air-conditioning in some trains also caused train disruptions.
